John Kerry is pushing for a costly global emissions treaty and Hillary Clinton testified at her confirmation hearing that "climate change" an "unambiguous security threat." But it appears a majority of Americans don't buy the theory of anthropogenic global warming. Rasmussen reports:

Forty-four percent (44%) of U.S. voters now say long-term planetary trends are the cause of global warming, compared to 41% who blame it on human activity.

Seven percent (7%) attribute global warming to some other reason, and nine percent (9%) are unsure in a new Rasmussen Reports national telephone survey.

Fifty-nine percent (59%) of Democrats blame global warming on human activity, compared to 21% percent of Republicans. Two-thirds of GOP voters (67%) see long-term planetary trends as the cause versus 23% of Democrats. Voters not affiliated with either party by eight points put the blame on planetary trends.

In July 2006, 46% of voters said global warming is caused primarily by human activities, while 35% said it is due to long-term planetary trends.

In April of last year, 47% of Americans blamed human activity versus 34% who viewed long-term planetary trends as the culprit. But the numbers have been moving in the direction of planetary trends since then.
